Meniscus fragments are generally non-absorbable, and if the fragments are large enough to interfere with knee motion, surgery is required to clean out the joint cavity. The meniscus is located in the joint space of the knee joint and consists of fibrocartilage in the form of a semi-circumferential ring, which has the function of cushioning, lubricating and protecting the joint. If the meniscus is torn due to trauma, overweight, etc., the fragments become free in the joint cavity of the knee, affecting the function of the knee, and symptoms such as knee pain and popping can occur. Fragments of meniscus are usually not absorbed. If the fragments are large and affect the normal activities of the knee joint, surgical treatment is needed to clean the joint cavity under arthroscopy. After checking and finding the meniscus fragments, it is recommended to take into account your own situation and be treated under the guidance of your doctor.
